The following would indicate you must take the credit in the year you purchase the qualifying vehicle. You can amend your 2023 tax return if you have the qualifying information.
Effective July 1, 2023, the innovative motor vehicle credit increases to $5,000 for the purchase or lease of a qualifying electric or plug-in hybrid electric vehicle. This increase does not apply to the innovative truck credit, which will increase for tax years beginning on or after January 1, 2024.
The Innovative Motor Vehicle Credit is open to Colorado residents who take possession of an eligible vehicle on July 1st, 2023 or later. Notably, there is an MSRP cap of $80,000, but that still leaves plenty of popular vehicles eligible. Unlike the federal tax credit requirements, the MSRP does not vary between vehicle types.
